Question

Question 7 Which of the following is the result of gene expression regulation? Because of gene expression: Fraternal siblings do not looking identical despite sharing 50% of their DNA Parents can pass on their genes to their offspring Parents can combine their DNA while diving their genome in half Cells can make copies of their entire DNA genome and pass it on to daughter cells Cells from different tissues can act and look differently despite sharing 100% of their DNA • Previous

Answer 1

Question 7. The correct option is Option e. Cells from different tissues can act and look differently despite sharing 100% of their DNA. This is due to differential gene expression.

If the Florida panther indeed becomes a separate species, it would have been because of Allopatric speciation because in this type a new species arises due to geographical isolation which prevents gene flow and leads to a new species.

In order to make the smallest monophyletic group that includes the Florida panther and Texas cougars, we must include b. The Eastern cougar. The monophyletic group means a group of animals with a common ancestor so to form a monophyletic group of Florida panther and texas cougars we must include Eastern cougar as they are showing to be originated from a common ancestor.
